„In the future, your office might have an extra appliance next to the copy machine and the refrigerator: an algae bioreactor. Designed to fit inside offices and eventually sit on the rooftops throughout cities, it can capture as much carbon from the atmosphere as an acre of trees. And there’s an initial prototype already at work.“

Sagues, William J.; et al. (2019): Enhanced carbon dioxide removal from coupled direct air capture–bioenergy systems
Sagues, William J.; Park, Sunkyu; Jameel, Hasan; Sanchez, Daniel L. (2019): Enhanced carbon dioxide removal from coupled direct air capture–bioenergy systems. In Sustainable Energy Fuels 5, p.[nbsp]230. DOI: 10.1039/C9SE00384C.
„Engineered carbon dioxide (CO2) removal technologies—such as direct air capture (DAC) and bioenergy with carbon capture and sequestration (BECCS)—require significant advancements to reduce costs and increase scale without environmental or social harm. Up until this point, advancements in BECCS and DAC technologies have progressed independently of each other, despite the ability of BECCS to provide carbon-negative heat and power to DAC processes. Here, we demonstrate synergistic integration of BECCS and DAC systems decreases costs, increases carbon removal, and extends the impact of scarce biomass resources.“
Global News Wire: Carbon Engineering expanding capacity of its commercial Direct Air Capture plant to provide negative emissions to customers
„Canadian clean energy company, Carbon Engineering Ltd. (CE), today announced it is expanding the capacity of the design for its first commercial Direct Air Capture (DAC) plant, to enable corporate customers to permanently remove carbon dioxide (CO2) emissions from the atmosphere. The plant is being expanded from a capacity of 500,000 tons, to an expected one million tons of CO2 removed from the atmosphere and permanently stored underground each year. The planned facility is being engineered in partnership with Oxy Low Carbon Ventures, LLC (OLCV), a subsidiary of Occidental and a leader in safe CO2 management and injection.„
„We’ve just lived through the four warmest years on record, say scientists. And in Switzerland, temperature rises are twice the global mean.“

„Machines that suck CO2 directly from the air could cut the cost of meeting global climate goals, a new study finds, but they would need as much as a quarter of global energy supplies in 2100.“

„This paper explores policies for Negative Emissions Technologies (NETs), in an attempt to move beyond the supply-side focus of the majority of NETs research, as well as the current dominance of carbon pricing as the main NETs policy proposal. The paper identifies a number of existing policies from four key areas[nbsp]– energy/transport, agriculture, sub-soil, and oceans[nbsp]– which will have an impact on three NETs: Bioenergy with Carbon Capture and Storage (BECCS), Direct Air Capture (DAC), and terrestrial Enhanced Rock Weathering (ERW).“
„The idea of removing carbon dioxide from the atmosphere as a method of combating climate change is nothing new. For the past 20 years, climate experts have included this strategy in their models showing theoretical pathways for avoiding catastrophic climate change — all of that data has been calculated based on the ability of plants to capture and store carbon in their biomass.“
„Scientists have developed a new way of achieving artificial photosynthesis, producing high-energy hydrocarbons by leveraging electron-rich gold nanoparticles as a catalyst.“
MIT Technology Review: Why the world’s biggest CO2-sucking plant would be used to … err, dig up more oil?
„A Canadian startup plans to build the largest carbon dioxide removal plant in the world, capable of sucking half a million metric tons of the greenhouse gas out of the air every year. If the project is ultimately built, it will represent a big step forward for direct air capture, a technology that a growing number of studies find could be essential for preventing dangerous levels of global warming. But it comes with a catch.„
